' Application filed June 5, 1908. Seria1 No.436,873.

Bei known that 1, CHARLES SSHALLEN- panama, a citizen of the United States, resid-v mg at St. Louis, Missouri ,have invented a a certain new and usefullmprovement in Car- Trucks, of which the following is a full, clear,

and exact description, such as will enable others skilled in the art to which it appertains I to make and use the same, reference being 4 part of this'specification,ihwhich- Figure Us a side elevational' view of a portion ofa car truck constructed'in accordance with my invention; and Fig. 2 is a top plan view thereof}; 1 j

This invention relates to a new and useful improvement in car trucks.

can truclgof the type shown and described 1s provlded with side frames having bolster receiving openings and columns which form the sides of said 0 enings, the

bolster being slidingly mounted etween said columns. In a truck of this type the shocks caused by stopping and starting the car cause the bolster to strike very severe ham mer blowson the upper portion of the columns, and these hammer blows very often break or crack said columns, I In accordance with my invention the'upper portion of each column'is provided with a palrof rlbs on its inner-face w ich strengthen the u as gul es for the bolster.

Referring to the drawings, A indicates truck sidefralnes, each of which is preferably in the form of a'single casting provided with a bolster-receiving open ng 1. Thejsidos of .thejo'pening are formed by columns 2, the

up er portion of each column 2 being prov1 edwith 'a pair of ribs 3 on its inner face.

- Theinner faces of the columns and the ribs 3 form channel-shaped guid'eways and the bolster Bis provided with lugs 4 which are ar- 9 r c! Q I ranged in said guide-ways. bprmgs 5 are interposed between the bolster and spring seats 6. 4

Toremove the bolster from the truck the Y first step is toremove the strings 5 and allow the bolster to drop onto 't 0 spring seats 6.

er portion of the columns and serve hadto the accompanying drawings, forming is'olaimed as new and desired to be secured by Letters Patent is:

When the bolster is resting on the spring seats its guide lugs are out of alinement with the ribs 3 and it can be moved longitudinally through the openings intheside frames.

I do notdeein it necessary to show or de- I scribe the wheels, journal boxes and the vari'- ous tie bars which are usually employed on a car truck as these elements forin'no part of this lnvention. Having thus described the invention, what 1. In a car truck, side frames each having a bolster-receiving opening, columns forming the sides of said opening, the upper portion of eachof said columns being provided with a pair of ribs, a bolster mounted between said columns and having guide lugs each of which projects into the space between a pair of said ribs, spring seats, and springs interposed between said bolster and spring seats; substantially as described. v

2. In a car truck, side frames in the form of castings each having an opening, columns forming the sidesof said opening, the upper portion only of eaclrof; said columns being columns belngprovided wlth a air of ribs which. are formed integral with t 10 columns and spaced apart so as to form a channelshaped guideway for a bolster substantially as described.

In testimony whereof I hereunto ailix mysignature in the. presence of two witnesses,
